provide an improved page end indicator for which typewriting or other printing machines in which a piece of ,paper is fed from one line printing position to another.

' My invention consists in certain features of construction and. combinationseand ar- I rangements of parts, all of which will be fully set forth herein and particularly pointed out in the claims.

One embodiment of my invention is illustrated in the accompanying drawings, in

Figure 1 is a front View of the upper part of a Smith Premier No. 10 typewriter ineluding-the platen and the carriage but with the top plate broken away, and other parts -broken or in section, and said typewriter having my invention applied thereto. Fig.

2 is a left-hand end elevation of the upperv rear part of said typewriting machine but with one end piece of thecarriage sectioned away and with some parts omitted. Fig. 3 is a fra mentarycentral section takenv longitudinfily of the platen and showing the left-hand end of the platen and associated parts on an enlarged scale. Fig. 4: is an isometric view,'on the same scale as Fig. 3, of a retaining friction plate. My invention is applicable or adaptable generally to printin devices having a paper feed of the sort usually employed in cylinder platen typewriters such for example as list adding machines and type-writers. The invention can-be used on visible typewriters or on those of the bottonrstrike variety. In the present instance 1 have shown it applied to a Smith Premier No. 10 typewriter, which a front-strike machine. This machine comprises the usual keys, type bars and ribbon mechanism,none of which is shown in the drawings. The main frame of the machine comprises a top. plate 1 which supports a stationary carriage rail 2 on which a carriage 3 is mounted by means of ball or roller bearings t. The carriagehas endpieces 5 in which. a platen frame 6 is ivotedi on pivot; pins 7. In Fig. 2' the left- 7 and end piece-5 has been! sectioned away so as better to show the construction of the platen frame and one of said pivot pins. A platen or paper roller 8 is mounted in. the

. platen frame 6 by means of'a shaft 9 which is journaledin. said laten. frame. At its right-hand endthe p aten carries a toothed line space wheel 10: which is. operated by a line space. pawl 11 mounted onv a rock shaft 12 having spacing lever mounted thereon, saigil away in. the drawin The line space wheel is. also: controllef by detent roller 13. In the present instance the ever, however, being sectioned a spring-pressed linespace wheel: has thirty-three teeth. The

platen is equipped with the usual fingerv wheels 14 by which it may be turned; A

paper table 15, extending upward and: rear ward from the back side of the platen,

guidesthe paper-to the platen or between the platen and a rear feed roll 16. The machine'isequipped also with a forward feed roll 17, a platen and carriage scale plate 18 and theusual paper apron, the last, however, not being shown.; Forthe purposes of the present invention it is desirable that the paper table be rather a wide one, as indicated in Fig. 2, althoughthis is not essential.

My invention, in the embodiment of it here shown, comprisesan annular scale or indicator 20 mounted on the left-hand end of the platen and of substantially the same diameter as the platen, this scale having imprinted on its periphery suitable indices 21 which in the present instance are shown as the numbers from 0 to 32 inclusive, these numbers being spaced to correspond with the spacing of the teeth of the line space wheel 10. The scale or. indicator 2() is nrade rotatively adjustable relative to the platen. suitable manner. in the prment instance the scale is mounted: on the end of the platen and provision is made for friction to retain the scale in any position to which it may beset with relation to. the platen, lent allowing it to be turned readily by hand to any desired extent. In the, present machine the platen has a left-hand platen head 22- which is secured to the end of the platen.

This may be accomplished in any ranged to fit circumferentially around the edge of this platen head and said scale is formed with an internal annular flange 24 that lies against the left-hand face of the platen head. Said scale is retained in place on thev platen head by a retaining device 25 which consists of an annular plate of sheet metal dished in at its middle part and secured to the face of the platen head 22 by means of screws 25 which pass through holes 27 in the plate 25 and are threaded into the platen head. The plate 25 has an outerflat rim 28 that lies against the outer face of the flange 24. It is desirable to press said flange with spring pressure against the platen head. This may be done in any one of a number of ways, but as here shown, said flange is cut out by slots 29 to form spring tongues 30 which are bent as shown in Fig. 4 out of the general plane of the flange 28. When' the plate 25 is placed in position on the platen head these spring tongues 30. are placed under tension, pressing against the flange 24 and placing the scale 20 under frictional restraint against turning relative to the platen but allowing said scale to be turned by hand.

A pointer 31 is arranged to cooperate with the scale 20, said pointer, as shown in the present instance, consisting of the pointed end of a suitably bent arm 32 WlllCh is secured by a screw 33 -to the leftThand end piece of the platen frame 6. The pointer 31 may be disposed in any suitable position about the scale 20, the only essential thin being that it be where it is plainly visilfie to the operator.

The paper table 15 is ruled with a series of parallel lines 34 extending transversely of the machine and parallel to the platen and spaced apart a distance equal. to the distance that the paper is fed when the platen is turned one tooth space of the line space wheel. As here shown these lines are near the left-hand side of the paper table and they are made of some length so as to cooperate with ieces of paper of different widths. These lines are numbered consecutively with numerals'35, the top line being numbered 33, the next one 32 and so on in order as faras the lines are sufiiciently visible to the operator to be of service. In

' opposite one of said lines 34, the correthe The lines 34 and numerals 35 are so disposed that, when the bottom of a sheet ofpaper stands sponding numeral 35 shows the number of hnes that it is still possible to write on the paper with single spacing. For example, when the bottom of the paper is at 30 single spacing, or-fifteen lines with double spacin before the bottom of the paper is reached. The scale consisting of the hnes present instance the numbering runs from 33 to 920 inclusive.

is possible to write thirty lines m0rewith .proceedTwith her work.

iece of paper has reached any point in its ceding rough the machine where its bottom edge lies adjacent one of the lines 34,

the operator can set the scale 20 by reference to the scale 34, 35. Thismay be done whenever the operator happens to think of it, provided the bottom of the sheet is over the scale34. As shown in Fig. '1 the lower end of the paper has reached the line on the scale 34 marked 30 Observing this the operator will set the scale 20 so that the number 30 is opposite the pointer 31;

'thisbeing done, the writing is proceeded with. It willbe noted that when the bottom of the paper reaches line 29 the numeral 29 on the scale 20 will stand oppo-' site the point 21. When the bottom of the paper reaches 25 on the scale 34 the numeral 25 of the scale 20 will then be opposite the pointer 21, and so on. It will thus be seen that at anytime when the bottom of the paper is opposite any part of the scale .34, the'operator notin this fact may set the scale 20 to correspon and that from that time on said scale 20 will indicate the number of single line spaces remaining on the sheet. The device thus indicates what line is being written on, and it also indicates the approach of the end of the page. If the operator-wishes to stop the writing at four single line spaces from the bottom, she will remove the paper from the machine when the numeral 4 on the scale 20 reaches the pointer 31. It will, of course, be understood that the device can be used to indicate any other point on the paper, as well as the end of the page, if desired.v

So far as I am aware it is broadly 'new to provide an adjustable line indicatorin com bination with a separate device or means coiiperatin with the paper and by reference to which said line indicator may be set or adjusted' If during the feed of'the paper from line to line as the writing is done, the operator neglects to set the scale 20 until after I the bottom of the sheet has passed oif of the scale 34, she can turn the platen backward untilthe bottom of the sheet appears some where on the scale 34. -She may then set the scale 20 to the numberfdetermined by an inspection of the scale 34 and turn the platen forward again to the writing line and It will be seen that both the scale 34,: 35 and the scale 20, constitute line indicators and page-end indicators; that one. of these ,may be made in the details moves with the paper roller and the other is relatively stationary; and thatone of them is set by the other.

It will be obvious that various changes of construction and arrangement without departing from my invention.

, WVhat I claim as new and desireto secure by Letters Patent, is

1. .In a typewriting machine, the combination of a paper roller, a fixed scale in position to cooperate with the bottom endof a sheet of paper and having numerals designating line space distances, and a second scale adjustably mounted on said paper roller and having numerals, corresponding with the numerals on the fixed scaleso that the said adjustable scale can be set in barmony with the fixed scale and. will continue in harmony therewith as the paper roller is turned.
